.DETACHABLE HINGE.

.Application filed February 271, 1921. Serial No. 446,889.

To .all Awhom lif may concern.'

Be it known that I, FREDERICK Hier-L' MANN, a citizen ot the United States, and residente-i' the city of St. Louis, andState of Missouri, have invented certain new and useful Improvements in VDetachable Hinges,

containing a iull, clear,'and enact 'description, reference being had to thefaccompanying drawings, forming a parthereof.

My invention relates to improvements in removable hinge covers, and has for its primary object the construction of a removable hinge cover for kitchen utensils, such 'as skillets and pans of various forms and sizes,

Y whereby the cover may be readily removed and applied and the cover opened and closed without entirely removing it from the utensil.

In the drawings:

Fig. 1 is a side elevation of a skillet having my improvement applied thereto; c

Fig. 2 is a side elevationo my improvement, the lid or cover being partly in section and broken away; f

Fig. 3 is a perspective view of one of the parts orp my improvement which is detachably connected to the cover or lid;

Fig. 4 is a front elevation of my improvement;

Fig. 5 is a plan view of one of the parts of my improvement stamped out of sheet metal and before being formed;

Fig. 6 is a plan view of another part of my improvement when stamped and before being bent into form;

Fig. 7 is a top plan view of a .skillet having applied thereto a modified iorm of my invention g y Fig. 8 is a side View of a modified form of my improvement, with parts broken away and in section;

Fig. 9 is a perspective view of a modified form of my improvement wherein it is permanently attached to the lid;

Fig. 10 isa plan view of said part before being formed; Y

Fig. 11 is a perspective view of the clip employed in the modified form of myinvention for holding the lid closed; f

Fig. 12 is a plan view of the clip before being formed; and .t

Fig. 13 is a plan View of the spring which I employ in the modified form of my imn provement. v

Referring to the drawings:

14: indicates an ordinary-skilletv and 15 the lid therefor. My improved device consists of a spring clamping device which may be applied over the edge of the utensil, and consists of a .spring arm 1G which is adapted to yieldingly Contact against the inside surface of the wall of the vessel, and is also provided with a spring arm 17 which is Vadapted to yieldingly contact with the outside surface of the wall of thevessel, and is provided with a portion 1S adapted to rest on the top edge of the vessel. l

Formed integral with the spring arm 17 are upturned prongs 19 and formed integral with the arm 17 are a pair of trunnions 20. These trunnions are adapted to be inserted in the eyes 21 formed on the member 22 Vwhich is attached to the lid or cover 15. The member 22 is provided with spring arms 23, which are adapted to grip the cover on its underneath surface and with the spring arm 2.4-, adapted to gripthe cover on its top surface. In this construction my improvement is designed to be detachably connected to the lid or cover.

In Figs. 7, 8, 9, 10, 11, 12 and 13, I have shown a modified form of my improvement. In this construction my improvement is permanently attached to the` lid by means of rivets 25 passing through the portion 26 and the lid. In this modified construction, my device forms a permanent attachment Vto the lid or cover.

In the modified form of my improvement I also employ a spring 27 having a portion 28 and arms 29, and eyelets 30, and insert the trunnions 2O in these eyelets, the portion 28 ofV the spring resting against the inside surface oi' the spring arms 17 and the arms 29 resting on each side of the spring clamp between the lid and the top edge of the vessel. In this construction the lid or cover is opened by the spring when the clip 31,

' mounted on the handle V32, has been disen' gaged from the lid or cover. In the modiied form of my improvement, when the lid 'trated lin Fig. 4Legainst which it rests, VWhereas) in the modified form the 'lid' or cover is opened by the spring 17, and in both forms of my device it is not necessary to en- 10 and itis adaptable .to iform .a hinge connecv open same.

i tion betvveentlie .utensil and the llid or cover.

Having fully described my invention, what I cleimfi:

l, A' removable Lhinge, comprising a spring4 clamp formed of two opposing 'spring arms curvedA towards erich other, iin upward-:ly .curved `extending iprojection formed integral with thelouterone of said farms, e 'pair of .trnnnions formed integral `with saidclmnp, a :clamp provided with `zi pair of `*perforated .ears mounted .on -said =s rinfr arms for en a in" C) C:

trunnions, said last mentioned clump having the up )er :1nd lower surfaces of a lid for detnchaiily connecting said lid to the hinge.

12.v A removable hinge, comprising :i

vspring vclamp formed of two opposing spring arms curved towards each other, an upwardly curved extending projection formed integral with the outer one of said arms orholding n lid when in open position, a pair of trunnions formed integral with said clamp, a clamp provided with n pair of perforated ears mounted on said trunnions, I:

said last mentioned clamp having spring arms for engaging the upper und .lower Surfaces `of a :lid for detnchnhly connecting said lid to the hinge, n spring carried by said hinge for lifting said lid5 und menne :for

holding said .lid yin closed iosition.

In `testimony whereof, have signed my name to this specifica-tion.

FREDERICK HACHMANN.
